Let's divide both sides of the equation by 4: x² + 2x - 4 = 0. Now, you can use the quadratic formula with a = 1, b = 2, and c = -4. We can now square root both sides to give: x+4=0. Now subtracting 4 from both sides gives x=-4. This means that for x^2+8x+16=0 we have found that x=-4. \displaystyle -2 and whose product is \displaystyle 3 \left ( -16 \right ) = -48; these numbers are \displaystyle -8,6. \displaystyle 3x^{2} -8x + 6x - 16 = 0.
